-The Cancellation library
-========================
-
-Intro
------
-
-This small library provides primitives for implementation of a cooperative cancellation of long running or asynchronous operations.
-The design has been copied from the well-known CancellationTokenSource/CancellationToken classes of the .NET Framework
-
-To use the library include `cancellation_token.h`.
-
-Examples
---------
-
-1. Simple check for cancellation
-
-    ```c++
-    void LongRunningOperation(TCancellationToken token) {
-        ...
-        if (token.IsCancellationRequested()) {
-            return;
-        }
-        ...
-    }
-
-    TCancellationTokenSource source;
-    TThread thread([token = source.Token()]() { LongRunningOperation(std::move(token)); });
-    thread.Start();
-    ...
-    source.Cancel();
-    thread.Join();
-    ```
-
-2. Exit via an exception
-
-    ```c++
-    void LongRunningOperation(TCancellationToken token) {
-        try {
-            for (;;) {
-                ...
-                token.ThrowIfCancellationRequested();
-                ...
-            }
-        } catch (TOperationCancelledException const&) {
-            return;
-        } catch (...) {
-            Y_FAIL("Never should be there")
-        }
-    }
-
-    TCancellationTokenSource source;
-    TThread thread([token = source.Token()]() { LongRunningOperation(std::move(token)); });
-    thread.Start();
-    ...
-    source.Cancel();
-    thread.Join();
-    ```
-
-3. Periodic poll with cancellation
-
-    ```c++
-    void LongRunningOperation(TCancellationToken token) {
-        while (!token.Wait(PollInterval)) {
-            ...
-        }
-    }
-
-    TCancellationTokenSource source;
-    TThread thread([token = source.Token()]() { LongRunningOperation(std::move(token)); });
-    thread.Start();
-    ...
-    source.Cancel();
-    thread.Join();
-    ```
-
-4. Waiting on the future
-
-    ```c++
-    TFuture<void> InnerOperation();
-    TFuture<void> OuterOperation(TCancellationToken token) {
-        return WaitAny(FirstOperation(), token.Future())
-                    .Apply([token = std::move(token)](auto&&) {
-                        token.ThrowIfCancellationRequested();
-                    });
-    }
-
-    TCancellationTokenSource source;
-    auto future = OuterOperation();
-    ...
-    source.Cancel()
-    ...
-    try {
-        auto value = future.ExtractValueSync();
-    } catch (TOperationCancelledException const&) {
-        // cancelled
-    }
-    ```
-
-5. Using default token when no cancellation needed
-
-    ```c++
-    void LongRunningOperation(TCancellationToken token) {
-        ...
-        if (token.IsCancellationRequested()) {
-            return;
-        }
-        ...
-    }
-
-    // We do not want to cancel the operation. So, there is no need to create a cancellation token source
-    LongRunningOperation(TCancellationToken::Default);
-    ```
